If cabin heating changes while the car is charging, record the charging state and the climate settings together. A complaint that occurs only while plugged in is different from heating that fails during normal driving. The relationship is evidence to investigate, not proof of a shared failed component.
Keep both timelines
Note whether heating stops when charging starts, when charging ends or after a period of operation. Include outside temperature, battery percentage and any vehicle or charger messages. Preserve settings for scheduled preconditioning and any recent software changes.
Identify the expected operation
Consult the handbook for the specific vehicle’s parked-climate behaviour. HELLA’s thermal-management overview describes why heating, cooling and electrified powertrains must be considered as a system; the exact control strategy remains vehicle-specific.
Send AXION the combined symptom and charging record. Ask whether an appointment can include the relevant operating condition. Do not open high-voltage heating components or refrigerant circuits to investigate. A clear history helps establish whether the next step is a settings check, software review or physical system assessment.
